because the man behind me in the queue thought I was!
I had just dropped dd at school, petrol light came on and I had 25mins before ds was due into pre-school. So I thought I'd pop to the local petrol station which has a Tesco metro attached (ie petrol is something else but you go into the Tesco to pay) Brilliant I thought I can pick up some porridge as we ran out this morning.
So I fill up, pop in and literally walk down 2 isles, pick up porrdge and weetabix and then think i'll treat myself to a pan eu chocolat for brekkie. It took about a minute.
Then I queue to pay, which probably takes about 2 mins.
Not unreasonable I thought until I walk out onto the forecourt and the in the car behinds starts shouting at me
Apparently he was now late getting his dd to school and it was my fault. 'park over there and get your f&ing shopping'
For a start there was a MASSIVE Tesco lorry blocking the shopping spaces. Perhaps he couldn't see it 
He then carried on as I got into my car, 'you've wasted 2 mintues of my life'
ROFL!!!
I was so embarrassed but I hadn't done anything, yet EVERYONE was staring at me
So was I BU by buying 3 things taking about a minute or am I right in thinking this > probably should rise out of his pit earlier to get his dd to school and perhaps not shout people down in petrol stations!!
